[rygel] core: Check received data size

[Zeeshan Ali Khattak <zeeshanak src gnome org>]

commit 364e9b1b6a775d379b33c739cf9b98e7cef513cd
Author: Jens Georg <mail jensge org>

    core: Check received data size
    
    If the server closes the connection gracefully during transfer, Soup
    doesn't give us an error. So we compare the expeted to the received
    number of bytes and set the state accordingly.
    
    Partially fixes UPnP CTT AV-CD:1-12.1
